ROAD-DRAG.

Specification of Letters Patent.

Patented Mar. 4, 1919.

Application filed March 16, 1917. Serial No. 155,318.

or leveler, the obj ect of the invention being to 1 0 v provide animproved machine of this character embodying blades of novelconstruction which serve to work the dirt toward the center of the roadand distribute and evenly pack the dirt.

The invention consists in the features of construction, combination, andarrangement of devices, hereinafter fully described and claimed.

In the accompanying drawings:

Figure 1 is a perspective view of a road drag constructed and arrangedin accordance with my invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a detailed horizontal sectional view of one of the blades.

In the embodiment of my invention here shown, a pair of blades 1 areemployed, one arranged in front of the other and each provided at itsupper side with a rearwardly extending flange 2. The blades areconnected together by bars 3 which are bolted lon the upper flanges ofthe blades and are arranged near the ends of the blades inclined, braces4 being provided for the blades and being arranged on the rear sidesthereof in the angles between the blades and the bars and being securedto the blades and the bars.

I also provide a pair of crossed braces 6 which are secured on the uppersides of the blades and are arranged between the bars 3.

Said bars 3 project forwardly from the blades and drag chains 7 areattached to the front ends of said bars as shown and beingk providedwith a ring 9 to'which the double-k tree or swingletree is hitched. Oneof the drag chains is longer than the other, so that the drag isarranged obliquely to the line of draft. K

Each blade is sinuous so that its lower and upper edges form compoundcurves. Each blade is also oppositely inclined at its opposite ends, sothat its front end 10 inclines upwardly rearwardly and its rear or innerend 1l inclines downwardly rearwardly as shown. Hence, when the drag isin use, its curved blades cut along the outer edge o-f the road, workthe dirt toward the center of the road and also evenly pack anddistribute thedirt and without leaving a ridge of dirt in the center ofthe road which is highly objectionable and which is ordinarily formed byroad drags or scrapers such as heretoforev used.

Having described the invention, what is claimed is:

A road drag comprising a pair of spaced parallel sinuous blades, theopposite ends of which are equally inclined in opposite directions, eachblade being formed with a horizontal rearwardly extending integralflange at its upper side, bars connecting the blades and bearing on saidflanges thereof and inclined braces on the rear sides of the blades,arranged in the angles between the blades and the bars and being securedto the blades andthe bars, said Vbra-ces bearing against the rear sideof said flanges.

In testimony whereof I affix my signature.
